Single-phase Voltage Relay
K8AB-VW
Ideal for voltage monitoring for industrial
facilities and equipment.
• Monitor for overvoltages and undervoltages simultaneously.
Separate settings and outputs supported for overvoltages and
undervoltages.
• Manual resetting and automatically resetting supported by one
Relay.
• Pre-alarm Monitoring Mode.
• Two SPDT output relays, 6 A at 250 VAC (resistive load).
• Process control signal (0 to 10 V) and current splitter input
supported.
• Output status can be monitored using LED indicator.
• Input frequency of 40 to 500 Hz supported.
• Inputs are isolated from the power supply.
Refer to Safety Precautions for the K8AB
Series. Refer to page 9 for the Q&A section.

Setting Method
1. Setting Voltage
The voltage knob (AL1 and AL2) is used to set the voltage.
The voltage can be set to 10% to 100% of the maximum measuring voltage.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the voltage.
The maximum measuring voltage will differ depending on the model and the input terminal.
Example: K8AB-VW3 Using Input Terminal V3-COM
The maximum measuring voltage will be 600 VAC/VDC and the setting range will be 60 to 600 V.
2. Operating Time
The operating time is set using the operating time knob (T).
The operating time can be set to between 0.1 and 30 s.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the operating time.
If the input exceeds (or drops lower than) the voltage setting, the alarm indicator will start flashing for the set period and then stay lit.
